Yesterday, we explored a critical issue in API workflows – Race Conditions! Many of you shared great insights, and now it's time to reveal the best practices to tackle this problem.
??? The Fix – Ensuring Data Consistency
1?? Implement Idempotency Keys
?? Assign a unique identifier to each API request to ensure the same operation isn’t processed multiple times. ?? Helps prevent duplicate or conflicting updates when retries happen.
?? Example: If System A sends an update request, System B should check whether it has already processed the request using an idempotency key before making changes.
2?? Use Versioning & Optimistic Locking
?? Every record update should include a version number or timestamp to detect conflicting updates. ?? If two updates occur simultaneously, the second one fails unless it has the latest version.
?? Example: When updating a database, the API checks if the version number is the same as before. If not, it rejects the update, prompting a retry with fresh data.
3?? Implement Database Transactions & Row Locking
?? Use ACID-compliant database transactions to ensure updates are atomic and consistent. ?? Apply row-level locking to prevent multiple processes from modifying the same record at the same time.

?? Example: In SQL databases, using SELECT ... FOR UPDATE can lock a record during processing, avoiding simultaneous modifications.
4?? Introduce a Queue-Based Processing System
?? Instead of making updates directly, queue the requests and process them sequentially. ?? Ensures that updates happen in the correct order without collisions.
?? Example: Workato can integrate with message queues like AWS SQS or RabbitMQ to handle API calls in a controlled manner.
? Key Takeaways
? Idempotency keys prevent duplicate updates.
? Optimistic locking ensures updates happen only with the latest data.
? Database transactions & row locking maintain integrity.
? Queue-based processing enforces sequential updates.
By applying these techniques, we can eliminate race conditions, maintain data accuracy, and ensure API stability! ??
